Modern physics has made immense progress over the last century or so, with general relativity and quantum mechanics at it's foundation. We've made countless tests of Einstein's general relativity, which have all passed with flying colors. We've discovered a whole world of sub-atomic particles. Our smartphones wouldn't exist without quantum mechanics, GPS wouldn't exist without general relativity. General relativity (GR) and quantum mechanics (QM) are the two cornerstones of modern physics. The problem is that they don’t happen to be the best of friends. GR applies to large scale things (think: galaxies and stuff), quantum mechanics applies ...
